We find that:
1) No site was consistently a source or a sink over time
2) Invasive species can have distant impacts on uninvaded
populations via fluctuations in native species’ local retention and emigration
3) Previously reported benefits of invasive prey attenuate over time

Happy to share new research, just out in Ecology @esajournals.bsky.social, led by Meghan Beatty.
We interrogate source-sink dynamics over a 28-year period for the endangered snail kite, testing how an invasion of novel prey alters dynamics...

Happy to say that I just finished the page proofs on the upcoming 2nd Edition of Spatial Ecology and Conservation Modeling!
Wow, that took some time (over 700 pages in this edition!)
Should be out in November!

I am excited to share new work led by Bob McCleery and with a wonderful group of co-authors.
Experimental evidence for the massive role that megaherbivores play in savannas...
And it is not just through their effects on vegetation...

Excited to be going to #BES2024 next week. I am keen to learn a bunch and meet new folks.
If you are there, please say hi!
(I am also talking about how we can unify connectivity science for conservation policy and management applications)

A few weeks ago, I started a new position in the Zoology Dept at the Univ. Cambridge, & linked w/ Cambridge Conservation Initiative.
Last night I gave an inaugural lecture & received a very warm welcome from the community. Thanks to everyone!
I really look forward to this next chapter!

Wonderful day in the field on the largest lake in the SE US!
Lots of conservation issues that urgently need to be addressed: water, wildlife, invasive species, recreation, and climate change!
